Canadian listed, Alphamin Resources Corp. (TSX-V: AFM) has released an updated, JORC compliant mineral resource for the Mpama North deposit, part of its Bisie tin project in North Kivu, DRC. Indicated resources total 2.65 Mt at 4.49% Sn, equal to 119,240 tonnes of contained tin, and inferred resources total 1.2 Mt at 3.6% Sn for 42,800 tonnes of contained tin, with both figures using a 0.5% Sn cut-off.

iTSCi is delighted to announce the start of iTSCi in two important areas of North Kivu, DRC; both in Lubero north of the Provincial capital of Goma, and in the most historically infamous 'conflict minerals' area of Walikale territory, west of Goma where the Bisie site is located. For several years prior to 2009, Bisie reportedly produced around three quarters of the cassiterite from the entire central African region and was alleged to be controlled by various military groups...

Australian based Stellar Resources (ASX-SRZ) has completed a metallurgical optimisation study which has increased potential tin recovery for the Severn deposit of the company's Heemskirk project in Tasmania to 79.5% Sn, a 7.1% improvement on the 2013 PFS.

Optimisations included elimination of a heavy media separation circuit, production of a coarser primary grind and removal of the silica flotation circuit, reducing tin losses and resulting in higher recoveries. The final concentrate will contain 45% Sn, within the optimum...

Long-running discussions on plans to limit tin exports were concluded on Monday with an agreement by most Indonesian producers to restrict their combined sales to 4,500 tonnes per month from April.

Bloomberg reported that the agreement was reached at meeting between smelters and officials from the Bangka Belitung provincial administration, according to Budiman Ginting, head of the provincial tin-working group. PT Timah will limit monthly exports to 2,500 tonnes per month and the balance will be divided among 21...

ITRI reports that eight of the top ten refined tin producers increased production in 2014, including all of the big four companies.

The companies included in the 2014 'top ten' producers table remains the same as the previous year. One of two notable changes in 2014 was PT Timah rising above Minsur, who ended the year in 3rd and 4th respectively. However, when production of 5,010 tonnes from Minsur's subsidiary, Taboca, is included, Minsur remains in 3rd position. Additionally, Yunnan Chengfeng...
